Invisibility seems a bit buggy. If you have the Invisibility effect active, then attack and go visible, you can't go back invisible until the effect time of the previously cast Invisibility wears off. That varies depending on the Unit's Level, as it increases as the Unit Levels up.
Code:
Lv.1 Lv.2 Lv.3 Lv.4 Lv.5 Lv.6 Lv.7 Lv.8 Lv.9 Lv.10
Game Turns 300 400 500 600 700 800 900 1000 1100 300
Seconds 15 20 25 30 35 40 45 50 55 15
The decrease in effect time at Level 10 is the cause of a different glitch.

Except for Skeletons, as they lack the ability to see invisibility... for some reason. Guessing the developers must have forgotten it, kinda hard to believe they'd make that intentional.
